Re: "Who are you ..." (Inspired by Thurber?)

: : : : what is the origin of the phrase "Who are you and what have you done with ..."
: : : : as in "Who are you and what have you done with my wife?"

: : : Rather than a phrase it sound like a sensible inquiry to make of the stranger you find in your home when you return from work and find that your wife is unaccountably missing.
: : I can't specify a first use, but it's a cliche from old movies.

: My God, has everybody forgotten the classic James Thurber cartoon "What have you done with Dr. Millmoss?"?

>>Inspired<< by Thurber maybe but I'd still like to track down first use of the longer phrase.
